.To all whom t mag/concern: v k

Be it known that l, RUDOLPH UROHNIAK, a subject of the Emileror ofAustria, and a resident of West lis, in the county of Milwaukee and State of Wisconsin, have invented new and useful llmprovements'in Envelop-Openers, of. which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in envelop openers. f

In opening ordinary envelops it fis the common practice to either tear of one edge portion of the envelop or to insert the end of a knife into-the envelop and cut through one edge thereof to gain access to 'the con- 'i tents of the envelop. Either plan isobjectionable on account of theliability of tearing or cutting the paper within the-envelop1 and in cases where the envelop contains checks lor other valuable papers the damage may causey a serious loss.

1t is one of the objects of the present invention to overcome .the before mentioned objectionable features and provide an en velop which maybe easily opened without the use of a knife or without tearing off the i edge portion of the envelop, thus obviating the liability of. injuring or destroying the contents of the envelop.

A further object of the invention is to vprovidean envelop with means whereby it may be opened in a very Simple manner and which means 1s of simple construction and does not materially increase the cost of thev 4 envelops.

With the above and other objects in view the invention consists of the improved envelopvopener and its parts vand combinations as set forth in the claiml and all equivalents thereof.

In the accompanying drawing in which -the same reference characters indicate the same parts in all ofthe views:

Figure 1 -is a view of the rear side of an envelop provided with the improved opener,

parts being broken away to show' interior construction Fig. 2 is a transverse sectional view taken on line 2-2 of Fig. 2; and

Fig. 3 is a rear view of the envelop in a slightly modified` form.

Referring to the drawing thenumeral 5 indicates an envelop of ordinary form which is provided with an opening lthread 6 extending within thel envelop and along one of the end creases 7 formed by the folded end flaps 8 of the envelop. The opening thread comprises the projecting portion orhandle 9, vthe angular extending anchored portion 10 and the medial cutting portion 11. The cutting portion 11 is lightly secured to the portion of the envelop forming'the end groove 7 by glue or other adhesive material 12 to hold the thread in position and to also Apermit it to be easily pulled laterally away from the paper in cutting through the edge 13 thereof. The anchored portion 10 of the thread is firmly attached to the adjacent right angled inner portion of the envelop by glue or adhesive material 12 so that the said end portion will not be pulled away from said inner portion while the handle -portion ofthe thread is being pulled to out the edge portion of the envelop-to be opened.

rllhe handle portion 9 of the thread conveniently projects from one of the corner edges of the envelop so it may be easily grasped by the fingers. j

The modified form shown in Fig. 3 differs from the principal form only in that the thread is adapted to open the end portion of the envelop instead of the upper edge portionas in Fig. 1 form.

From the foregoing description it will be seen that the envelop is of very simple construction and may be-easily opened without the liability of injuring the contents of the envelop.

. What l claim asmy invention is:

The combination with an envelop, of an opener therefor consisting of a length of thread having a handle portion, 'an 'anchored portion and a medial cutting portion, the cutting portion extending within and along the crease of'one of the folds of the. envelop, the anchored lportion of said thread extending at right angles from the cutting portion into the crease of' an adjacent fo'ld, and the handle portion projecting outwardly from the envelop, the cutting and anchored portions of the thread being glued' to the respective portions o f the envelop which they engage approximately throughout their length, the cuttin portion of the thread being s o lightly glue to the portion of the envelop which it en- In testimony whereof, l alixniy signagages as to freely separate therefrom when ture, in presence of tWo Witnesses.

pulled at am angle and the anchored portion RUDOLPH URCHNIAK being more securely glued to the portion of the envelop which it engages to maintain Witnesses:

opened by the angular pull of the thread. C. H. KEENEY.
